Richardson first began using a camera as a youngster on his parents' wheat and dairy farm north of Belleville in north-central Kansas. He began experimenting with his father's second-hand box camera, photographing the world of the farmstead for display at the Republic County Fair.
Now, his combined areas of expertise include volcanoes, agriculture, rivers and aquifers, and the United Kingdom, especially the people, culture, and landscape of Scotland, his family's native Cornwall, and the wider Celtic world. His work has made him a prized speaker and visual presenter around the world.
